My new hobby is to play VL2 virtual instruments on my Manjaro system by using a USB connected MIDI keyboard. I have chosen two VL2 VIs: the setBfree (Hammond organ) and the piano plugin mda.lv2. Both are available for free via AUR.
As I do not want to record or produce music, I do not want to install a real DAW. Instead, it seems, that installing Jack audio and running the Jack server should be enough, to get startet…. - I thought, based on all the information from the web and KI.
But actually, when I start the Jack server and open its GUI, there are only “system capture_1 and capture_2” and twice the element “14:Midi Through Port-0” – I suppose, that there is no connection active to Pipewire audio and Pulse audio.
When I start “setBfree”, it comes up with its own GUI and in the GUI of QJackCtl, its shows up with an element “setBfree DSP Tonewheel Organ” offering a control and a notify access-point and Out left / Out right.
Starting QJackCtl and then setBfree, then terminating setBfree and stopping QJackCtl server again will result in the following log output:

On my Manjaro, I have installed QJackCtl, Jack Mixer, jack2, Calf Plugin Pack for Jack (calf).
Further I have installed setBfree-standalone and x42-whirl and mda.lv2
As my Manjaro is running flawlessly, I have not added detailed infos here using inxi etc. But if required, I will add this info on request.
The information in the web about activating some services or setting up some groups like “realtime” etc. where very confusing for me. Also there has been sometimes the recommendation, to install jack2-dbus.
But I did not find the information, how I could proceed to set up these components, so that I can connect them in the Jack GUI successfully. Many explanations refer to the older pulse audio system and I don’t want to break my system by doing something, which is incompatible with pipewire audio.
Any helping hints are welcome!
